A lot of people have always worried about the security of bitcoin and cryptocurrency which is why they have decided to stay away from investing in it. You must also note that even the fiat money that you may have can also be liable to theft. The earlier you stop giving flimsy excuses, the better. The decision is yours!
Sometimes you cannot blame them for being worried about it. Crypto is so young and there is not guarantee that you could really rely on it. Fiat is good at all times since it is still being used by all people around the world. But also crypto can be a good alternative investment that you could put your money in for the meantime.
